Hope Someone Can Help

First a little backstory: I've been TTC for 11 months. Randomly in April I had a weird period that consisted of spotting off and on and a day or two of bleeding off and on but this lasted for 13 days. In May I had four day spotting on data period was supposed to show but the spotting was only existent when I wiped it never actually showed on pad. No period in June, July, or August. Period started back in September and I'm currently on day 10! Twice (tonight and last night) I've been laying here at 3:48am and all of a sudden I feel blood pouring out almost as fast as pee comes out then it stops. Any idea what is causing all of this? I have an appointment for October 1st I just wanna see if I can maybe get some kinda answers now.
